| Chromosome | 17 | NCBI Gene Number | 21354 |
| Mgi Type | protein coding gene |
| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 9.1.0) Enables ABC-type peptide antigen transporter activity and MHC class I protein binding activity. Acts upstream of or within defense response. Located in mitochondrion. Is expressed in several structures, including blastocyst-stage conceptus; cranium; early embryo; limb; and nervous system. Human ortholog(s) of this gene implicated in several diseases, including arthritis (multiple); bronchial disease (multiple); diffuse scleroderma; lung disease (multiple); and open-angle glaucoma. Orthologous to human TAP1 (transporter 1, ATP binding cassette subfamily B member). PHENOTYPE: Mice homozygous for targeted mutations that inactivate the gene are deficient in antigen presentation, surface class I antigens, and CD4-8+ T cells. [provided by MGI curators] |
